Mixer

Abstract

Provided is a mixer. The mixer comprises a mixing drum, a head cover is arranged on the mixing drum, a main pipe is installed on the head cover, a pressure type nozzle extending into the mixing drum is installed on the main pipe, a mist vent of the pressure type nozzle faces downwards, multiple mounting grooves which extend in the radial direction along the head cover and are evenly distributed in the circumferential direction are formed in the head cover, branched pipes which are communicated with the main pipe are installed in the mounting grooves, multiple pressure type nozzles extending into the mixing drum are installed on the branched pipes, mist vents of the multiple pressure type nozzles face downwards, the depths, extending into the mixing drum, of pressure type nozzles installed on the branched pipes are different from the depth, extending into the mixing drum, of the pressure type nozzle on the main pipe, head cover plates which cover the mounting grooves are arranged on the mounting grooves and hinged to the head cover, a big-end-down cone-shaped mist collecting cover is installed on the inner wall close to the edge of the head cover, and the diameter of the major diameter end is smaller than or equal to that of the head cover. According to the mixer, the radiating area can be larger when atomized absolute ethyl alcohol is sprayed out, the atomized absolute ethyl alcohol can make contact with carborundum in time to be mixed fully and evenly.

Description

technical field [0001] The invention relates to the technical field of production of silicon carbide products used in mechanical seals, in particular to a mixer. Background technique [0002] Before the silicon carbide powder (powdered silicon carbide mixed with other substances) is made into parts for mechanical seals, in order to increase the fluidity of the silicon carbide powder, the silicon carbide powder has a good flow effect during pressing , the current general practice is to mix silicon carbide powder with absolute ethanol to increase fluidity. [0003] For the mixing of the two, an ordinary mixer is often used to directly mix the absolute ethanol and the powder. When mixing, under the action of the high-pressure pump, the liquid absolute ethanol is input into the pressure nozzle by the high-pressure pump. Type nozzle to form atomized anhydrous ethanol. [0004] At present, the pressure nozzle is generally installed on the top of the mixing barrel, and the number...

AI Technical Summary

Problems solved by technology

The pressure nozzle adopts the above-mentioned layout to radiate the powder in the barrel with a small radiation area, and the powder in the barrel cannot fully and timely contact with absolute ethanol for mixing
